Description

Technical Field

[0001] This utility model relates to a switch panel, and more particularly to a kitchen switch. Background Technology

[0002] In a kitchen environment, multiple wall sockets are typically installed above the countertop to power various kitchen appliances such as rice cookers, microwave ovens, ovens, and kettles. Common kitchen sockets come in two main types: standard sockets with only power outlets, and combination sockets that integrate a switch and corresponding outlet. Users plug the appliance into the outlet. With combination sockets, users can control the power supply to the outlet by toggling the switch, eliminating the need to repeatedly plug and unplug the appliance. With standard sockets, users must plug in the appliance and unplug it after use to disconnect the power. Because kitchen appliances are often located in different areas, users frequently need to operate the different sockets individually, leading to fragmented management.

[0003] However, existing kitchen socket panel designs have significant flaws. Panels with switches reduce the number of sockets due to the space occupied by the switches, thus limiting the number of appliances that can be connected. While panels without switches have more sockets, they require frequent plugging and unplugging, which is inconvenient, causes wear and tear, and poses safety hazards. More importantly, each panel operates independently, making it impossible to centrally control the power supply of other sockets from a single point. Users cannot easily disconnect the power to multiple appliances with a single button, leading to increased standby power consumption and management risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a kitchen switch that allows for centralized control of the on / off state of multiple socket circuits.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a kitchen switch, comprising a panel, wherein at least one set of corresponding sockets and a control component for controlling whether the sockets are powered on or off are provided on the panel, and a main control component, wherein the main control component comprises a main power input terminal, a first power input terminal for connecting to other switches, and a second power input terminal for connecting to the control component on the panel, wherein the first power input terminal and the second power input terminal are the only power input terminals of the switches and control components connected thereto, respectively, and the main control component can control the connection or disconnection between the main power input terminal and the first and second power input terminals.

[0006] The beneficial effects of this utility model are as follows: By centrally controlling the power supply of the panel's built-in socket and other external switches, users can simultaneously cut off the power to multiple circuits through a single central control unit, eliminating the need for frequent plugging and unplugging of appliances, reducing plug wear and standby power consumption, and improving the convenience and safety of kitchen electricity use. The two branch power input terminals serve as the sole power input terminals for downstream circuits, ensuring complete control of all downstream circuits by the central control unit and preventing uncontrolled branch circuits. As a preferred embodiment, the central control unit adopts a double-pole linkage contact structure, synchronously controlling the conduction and disconnection of two branch circuits through the same operating element. The two branch circuits are electrically independent and can be adapted to different load circuits. As another preferred embodiment, the two branch output terminals of the central control unit can be short-circuited externally through a conductive component, merging into a single high-current output, suitable for single-circuit multi-load usage scenarios.

[0007] Furthermore, the first power input terminal and the second power input terminal are connected to the same conductive element.

[0008] Integrating the two branch power inputs onto a single conductive component reduces the number of internal conductive parts, simplifies the internal wiring structure of the main control assembly, and lowers assembly complexity. It also unifies the power supply potential of the two branches, preventing potential differences and improving power supply consistency and stability. Furthermore, it facilitates synchronous on / off control of the two branches by the main control assembly. As a preferred embodiment, the conductive component uses a one-piece stamped copper conductive sheet, with the two branch power inputs positioned on different extension arms of the conductive sheet, achieving synchronous conduction through a single moving contact. Alternatively, the conductive component features a plug-in wiring structure, allowing the two branch power inputs to share the same input terminal, reducing the number of external wiring steps.

[0009] Furthermore, the main control component includes a first copper component, a second copper component, a third copper component, and a fourth copper component. The main power input terminal is connected to the first copper component, the second copper component is connected to the neutral wire, the third copper component is connected to the first power input terminal and the second power input terminal respectively, and the fourth copper component is connected to one or more neutral wire terminals of the control component and other switches.

[0010] Four sets of copper components are used to construct separate live wire and neutral wire switching circuits, achieving synchronous control of both live and neutral lines. This forms a fully disconnectable master control structure, which simultaneously cuts off both the live and neutral wires when the switch is turned off, preventing downstream loads from becoming energized and improving electrical safety. The third copper component integrates the live wire outputs from two incoming power terminals, and the fourth copper component unifies the neutral wire circuit, simplifying the internal conductive layout and wiring process. As a preferred configuration, the first and third copper components form the live wire switching circuit, and the second and fourth copper components form the neutral wire switching circuit, with the two circuits symmetrically arranged on both sides of the master control component. Alternatively, the fourth copper component is configured as a common neutral wire conductor, capable of simultaneously connecting to the neutral wire terminals of both the internal control components on the panel and other external switches, achieving unified neutral wire connection.

[0011] Furthermore, the main control assembly includes two moving contacts and a control rod for synchronously driving the two moving contacts to move. The first copper piece, the second copper piece, the third copper piece, and the fourth copper piece are arranged to surround the moving contacts and are respectively arranged at the ends of the two sides of the moving contacts.

[0012] The system employs a control lever to synchronously drive two moving contacts, ensuring complete synchronization of the on / off actions of the live and neutral wire circuits. This avoids power anomalies caused by a single circuit switching out first, guaranteeing power supply stability at the load end. The structure of the moving contacts surrounded by copper components fully utilizes internal space, reducing the overall size of the main control assembly and adapting to the limited installation space within the panel, thus optimizing the internal layout. As a preferred method, the two moving contacts are symmetrically mounted at both ends of the control lever. As the control lever swings, the two ends synchronously contact or disengage from the corresponding copper contacts, achieving synchronous on / off switching of both circuits. As another preferred method, four sets of copper components are circumferentially distributed along the swing path of the moving contacts. Each end of the moving contact corresponds to one set of incoming copper components and one set of outgoing copper components, forming two independent on / off circuits.

[0013] Furthermore, the third and fourth copper parts are each provided with a contact point at the corresponding position of the two moving contact ends.

[0014] Setting independent contacts on the copper components on the outgoing side improves the contact stability of the moving contact during conduction, reduces contact resistance, minimizes heat loss during conduction, and enhances the arc resistance and wear resistance of the contacts, extending the switch's lifespan. The moving contact's surface contact with the contact point allows it to carry a larger operating current, meeting the needs of high-power kitchen appliances. As a preferred method, the contacts are made of silver alloy riveted to the surface of the copper components, corresponding to the end of the moving contact, achieving stable conduction of large currents through surface contact. Another preferred method is to design the contacts as a raised spherical structure, with the moving contact end as a corresponding planar structure. This automatically compensates for assembly errors during contact, ensuring reliable contact.

[0015] Furthermore, the control component includes a fifth copper component and a sixth copper component, which are respectively disposed on the upper and lower sides of the first power input terminal; the control component includes a neutral wire terminal, which is respectively disposed on the upper and lower sides of the sixth copper component and a fourth copper component.

[0016] By installing corresponding copper pieces on the upper and lower sides of the power input terminal and the neutral terminal, a clamping wiring structure can be formed, improving the connection strength after the external wire is connected and avoiding poor contact caused by loose wires. Simultaneously, the third and fourth copper pieces serve the dual function of providing both the main control output and the conductive connection, reducing the need for additional conductive parts and simplifying the internal structure. As a preferred method, the first power input terminal uses a screw-type wiring structure, with the fifth and third copper pieces acting as upper and lower conductive clamping plates for the wiring. Tightening the screw presses the wire firmly between the two copper pieces. As another preferred method, the neutral terminal uses a spring-loaded wiring structure, with the sixth and fourth copper pieces forming an elastic clamping channel. After the wire is inserted, the spring force achieves self-locking fixation.

[0017] Furthermore, it also includes a base, on which corresponding snap-fit ​​grooves are provided for each copper component.

[0018] The base features snap-fit ​​slots adapted to each copper component, enabling rapid positioning and installation, improving assembly efficiency, and providing multi-directional limiting and fixation to the copper components, preventing short circuits or poor contact caused by component displacement during use. The snap-fit ​​installation structure eliminates the need for additional fasteners, reducing the number of assembly parts and lowering manufacturing costs. As a preferred method, the inner wall of the snap-fit ​​slot has undercut protrusions; after the copper component is inserted into the slot, the undercuts provide axial restraint, preventing the component from detaching from the slot. Another preferred method is that the shape of the snap-fit ​​slot matches the cross-sectional profile of the corresponding copper component, and insulating ribs are provided between the snap-fit ​​slots of adjacent copper components to improve the insulation performance between copper components in different circuits.

Detailed Implementation

[0020] This utility model embodiment provides a kitchen switch, such as... Figure 1-3As shown: This kitchen switch includes a panel 1, on the surface of which is embedded at least one set of sockets 11. The sockets 11 adopt a conventional plug structure for connecting external electrical equipment plugs. Inside the panel 1, corresponding to the position of each set of sockets 11, a control component 2 is provided. The control component 2 is an independent switch structure, used to individually control the on / off state of the corresponding socket 11. The panel 1 also integrates a master control component 3, which has a master power input terminal 31, a first branch power input terminal 32, and a second branch power input terminal 33. The first branch power input terminal 32 is used to connect to the live wire input terminal of other external switches, and the second branch power input terminal 33 is electrically connected to the live wire input terminal of the control component 2 on the panel 1. The first branch power input terminal 32 is the only live wire input terminal for connecting other external switches, and the second branch power input terminal 33 is the only live wire input terminal for the control component 2 inside the panel. The master control component 3 can simultaneously control the conduction or disconnection of the circuit between the master power input terminal 31 and the two branch power input terminals.

[0021] The main control component 3 comprises four independent conductive components: a first copper component 34, a second copper component 35, a third copper component 36, and a fourth copper component 37, all made of copper, a material with excellent conductivity. The main power input terminal 31 is integrated onto the first copper component 34 and electrically connected to it, used to connect to the external main live wire. The second copper component 35 is a neutral wire input conductive component, used to connect to the external main neutral wire. The third copper component 36 is electrically connected to both the first branch power input terminal 32 and the second branch power input terminal 33, placing the two branch power input terminals at the same conductive potential, forming a common conductive structure on the live wire output side. The fourth copper component 37 is electrically connected to the neutral wire terminal 23 of the control component 2 and the neutral wire terminals of other external switches, forming a common conductive loop on the neutral wire output side.

[0022] The main control assembly 3 internally has two moving contacts 38 and a control lever 39. The control lever 39 is connected to the two moving contacts 38 via an insulating bracket, which can synchronously drive the two moving contacts 38 to swing around a pivot. A first copper component 34, a second copper component 35, a third copper component 36, and a fourth copper component 37 are arranged on the insulating base of the main control assembly 3 in a manner that surrounds the moving contacts 38. The four sets of copper components are respectively positioned at the two ends of the two moving contacts 38. Specifically, the first copper component 34 and the third copper component 36 correspond to the two ends of one moving contact 38, forming a live wire switching circuit; the second copper component 35 and the fourth copper component 37 correspond to the two ends of the other moving contact 38, forming a neutral wire switching circuit. A contact point 5 is provided on the third copper component 36 at a position corresponding to the end of the moving contact 38, and a contact point 5 is also provided on the fourth copper component 37 at a position corresponding to the end of the moving contact 38. When the moving contact 38 swings, it can achieve stable connection or disconnection with the corresponding copper component through the contact point.

[0023] The control component 2 includes two sets of conductive components, the fifth copper component 21 and the sixth copper component 22. The fifth copper component 21 and the third copper component 36 are respectively arranged on the upper and lower sides of the first power input terminal 32, forming a clamping wiring structure. With the help of the wiring screw, the external wires can be clamped to ensure the reliability of the connection. The control component 2 is provided with a neutral wire terminal 23. The sixth copper component 22 and the fourth copper component 37 are respectively arranged on the upper and lower sides of the neutral wire terminal 23, forming a clamping wiring structure on the neutral wire side.

[0024] The kitchen switch also includes a base 4, which is made of insulating and flame-retardant plastic material. The base 4 has matching snap-fit ​​grooves 41 on it, corresponding to the outline and installation position of each group of copper parts. Each group of copper parts is snapped and fixed in the corresponding snap-fit ​​groove 41, which can realize the quick positioning and installation of copper parts, and can also realize the insulation isolation between adjacent copper parts through the side wall of the groove.

[0025] The working principle of this embodiment is as follows: During assembly, the first copper part 34, the second copper part 35, the third copper part 36, and the fourth copper part 37 are first inserted into the corresponding slots 41 of the base 4. The side wall of the slot 41 limits the fixation and insulation separation of each group of copper parts. Then, the two moving contacts 38 and the control rod 39 are assembled to the corresponding rotating shaft mounting positions of the base 4, so that the two ends of the two moving contacts 38 correspond to the contact positions of the inlet copper part and the outlet copper part, respectively. Then, the fifth copper part 21 and the sixth copper part 22 of the control component 2 are installed to the corresponding positions of the power inlet end and the neutral end, completing the assembly of the internal conductive structure. Finally, the panel 1 is fastened to complete the assembly of the overall switch. In use, the external main live wire is connected to the main power input terminal 31 and then to the first copper component 34, while the external main neutral wire is connected to the second copper component 35. The live wires of other external switches are connected to the first power input terminal 32, and the live wire of the panel's built-in socket circuit is connected to the control component 2 through the second power input terminal 33. The neutral wires of both the external switches and the socket circuits are connected to the neutral terminal 23 and then converged to the fourth copper component 37. When the operating control lever 39 drives the two moving contacts 38 to swing synchronously, the two moving contacts 38 can simultaneously contact or disconnect from the contacts on the third copper component 36 and the fourth copper component 37, simultaneously realizing the switching on and off of the main live wire circuit and the main neutral wire circuit. This allows for the simultaneous control of the overall power supply to the panel's built-in socket and other external switches, achieving the effect of centralized control of multiple power circuits from a single point.

[0026] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
